6 Claims. (Cl. 235-133) This invention relates to improvements in adding and recording machines and more particularly to transfer mechanism coacting with the totalizer in which adding and subtracting operations are carried out during the totaling and listing operations of the machine.

The chief objects of the invention are the provision of novel and eilicient mechanism for accumulating totals or subtracting given amounts which includes new and improved totalizer units operable by direct engagement with the type bars or rack bars of an adding machine and having means coacting therewith and positively operated thereby to effect a transfer from one unit to another throughout the whole width of the machine when such functioning is necessary.

A further object is the provision of a totalizer having aligned and independently movable totalizer units operatively connected with each other in a novel manner that at predetermined intervals of their rotation in either direction, one of the totalizer units will eifect the positioning of the adjacent totalizer unit.

A still further object is the provision of a totalizer adapted to be bodily carried in a path for engagement with a plurality of rack bars that determine their rotating movements and detent means arranged for yieldingly retaining the units of the totalizer in the position to which they have been advanced while either in or out of engagement with the rack bars.

With the foregoing and other objects in' view, the present invention resides in the novel combination and arrangements of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made without departing from the spirit of the invention.

The present application is a division of my prior application, Serial No. 717,156, filed March 24, 1934, for improvements in adding and recording machines, and only so much of the machine shown and described in said application as is necessary for a full understanding of the subject matter claimed in this divisional application will be shown and described. Insofar as it has been possible to do so, the reference numerals appearing in the prior application have been employed to designate the corresponding parts herein.

To more clearly understand the operation of the transfer mechanism, I have explained in gen-' era] the construction and operation of parts con-.

trolled by the digit keys for withholding and releasing type bars which actuate the rotating movements of the units of the totalizer that control and which in turn are controlled by the transfer mechanism.

The numeral 28 designates the bottom wall of the adding machine to which a pair of side plates 29 and 30 respectively are secured and on which the working parts of the machine are supported.

A keyboard having a group of digit keys ll supported in rows or banks therein, is positioned between the side plates 29 and 30 and the keys are each provided with stems 33 which have their lower end portions 330. serving as stops for controlling the movements of reciprocating type bars when the keys are depressed. These keys are also aligned transversely and their stems 33 are each provided with a vertical slot opening 34 therein through which a shaft 32 extends for limiting its movement in either direction and each key is normally urged upwardly by means of a. compression spring 35. The key stems II Q on its top edge with a plurality of steps I 1 formextend through slot openings 88a. and 88a. respectively, in a top member 88 and a bottom member 89 of the keyboard. The key stems 88 are each provided on their forward edges with a cam surface 88 and a shoulder 81 which serve; upon the depression of a key. to move and lock a pair of slide members 48 and 48 which are carried on the bottom member 89 below each bank of keys. The slide members 48 and 48 are each provided with a plurality of slot openings 4| and 48 respectively through which the lower ends 88a of the key stems 88 extend. The slides 48 and 48 are arranged for sliding'movements on a plurality of studs 42, 48, 44 and 45 fixed to the bottom member 88 and are yieldingly held for movement in one direction against the tension of the springs 48 and 58, respectively, secured to the studs 41 and 51 of the respective slides and to the fixed studs 45 and 44 on the lower member 88.

A plurality of slide locks 84 are carried on a transversely extending shaft 55 carriedat the rearward end of the keyboard and these slide locks. are each arranged for movement with a slide 48 and are adapted to be rocked into the path of a transversely extending bar 285 which is actuated by the driving mechanism of the adding machine for locking the slides 48 in either their normal or changed positions.

Zero stops 58 are supported for free rocking movements on a transversely extending shaft 58 carried at the forward end of the keyboard and are for the purpose of selectively limiting the movement of the type bars to permit the zeros thereof to be automatically positioned in a printing line. A type bar stop 85 which is provided with a depending portion 88 is also carried on the shaft 59 adjacent each of the zero stops 58 and is controlled by the movements of the zero stop 58 with the depending portion 88 thereof normally in the path of the ear 18 on the coacting type bar 15. The type bar stops 85 are each provided with an angular formation 89 that projects over a forwardly extending portion 84 of the zero stop 58 and under an extending portion 18 of a type bar stop 85 in the adjacent bank of lower denominational order. The movement of 8| will rock the zero stop 58 on the shaft 58- and cause the extension 84 thereof to engage the angular formation 89 of the type bar stop 85 and the angular formation 89 will also engage the extension 18 of the adjacent type bar stop 85 in the bank of lower denominational order and position the depending portion 88 thereof free of the ear I8 of the coacting type bar I5.

The type bar stops 85 are yieldingly carried with the zero stops 58 against the tension of a spring I3 which is fixed to an inwardly extending ear 18a on the type bar stops and to a pin 14 fixed in a partition wall ii that extends between each of these units and which also serve as a spacer therefor. V

' forward ends with an ear I6 which is adapted to be engaged by the depending portion 88 of the type bar stop or by the depending portion 88 of the zero stop. Each of the type bars is provided ing stops which are adapted to be engaged by the end 88a of one ofthe selected depressed digit keys 8|. A type bar I5 is arranged for sliding movements below each row of digit keys 8| on a transversely disposed shaft 18 that extends through an elongated slot opening I8 in the type bars and is fixed in the side plates 29, and 88. The type bars I5 are also guided at their rearward end portions in the combs 8| and 83 which are also fixed to the side plates 29 and 38. -A full and complete description of the keyboard and its operation has been given in my application, Serial No. 751,812, filed November 7, l934, and it is thought that a brief description of the operating parts coacting with the type bars forming a part of this invention will sufiice.

Each of the, type bars 15 is provided with a long and relatively narrow slot opening 84 which serves to guide a driving rack 85 thereon by means of the studs 88 and 81 secured to the rack and extending through the slot opening 84. The rack 85 is normally urged toward the front end 84a of the slot opening 84 by means of a relatively long tension spring 88 which has one end secured thereto and its other end secured to a pin 88 on the type bar. The racks 85 are each in constant meshing engagement with a rack gear and has a driving gear 82 fixedthereto which is adapted to be engaged by a segmental gear 98 (Figs. 1, 2 and 7), which is fixed to a rockable I actuator shaft 94 that is positioned below the shaft 9| and which is also journaled in the side fixed to the shaft 9| adjacent the gear 92 and is adapted to cooperate with a geneva locking member 91 which'is fixed to the actuator shaft 94 to retain the shaft 9| locked against turning movements at each limit stroke of the ro'ckable actuator shaft 94. The geneva locking member 91 is provided with dwells98 and 89, respectively, at each peripheral end thereof which dwells coact with the convex surfaces I88 and I8I, respectively, formed on the edge of the geneva lock 98 which provide a space between the dwells 98 and 89 which permits of the free rotating movement of the geneva lock 98 and the rotation of the gear 92 with the segment 98 which is brought into meshing engagement with this gear, 92 as the.

actuator shaft 94 is rocked.

The type bars 15 are each provided with an ear |8|, (Figs. 2, 5 and 6), which is adapted to be normally engaged by means of a type bar lock arm I58 that is pivotally mounted on the shaft I81 andhas an integral depending arm I54 that '88 plates 29 and 38. A geneva type oflock 98-is is normally retained in the path of movement of a shaft I58 by means of a spring I58 fixed there-,=

to and to a cross member I51 fixed tothe-side plates 29 and 88. The shaft I58 is bodily carried for rocking movements with the actuator shaft 84 in the geneva locking member 81 and in a sector 3| I. As the actuator shaft 94 is rockedv forwardly or to the left, as viewedoin the drawings, the shaft I58 will engage the depending arms I 54 and effect a swinging movement thereof on the shaft I81 and release the arms I88 from the ears |8| of the type bars and permit the type bars to be driven with the actuator shaft until arrested by a depressed key.

When a key is depressed, the slides 48 and 48 coacting therewith will be caused to move forwardly by means of the cam surface 88 of the key stem 88 engaging the slot openings 4| and 49, respectively, of the slides, and the slide 48 will rock the zero stop 58, which, in turn, will rock the type bar stop 85 with the depending end 88 thereof, free of the ear 18 on the type bar 15 and render the type bar free to be driven as the actuator shaft 94 is rocked.

' Totclizer or teeth I82 which extend partially along" the lower edge thereof .and which are each adapted to be engaged by a unit of the totalizer A positioned below the type bars. The totalizer A is carried. on a pair of arms I03 and I04, respectively, which are pivotallysupported for rocking movements on the shaft 8| adjacent eachof the sideplates 28 and 30. The free ends of the arms Ij03and I04 are each connected to a regulating device I09 carried adjacent thereto in flxed'position on a shaft I05 that is journaled in theside plates 29 and 30.

The shaftsmarked I05, I01 and I08 are carried in the side plates 29 and 30 and support mechanism extending into the path of movement of the totalizer units A .for engagement therewith in either direction of the rocking movements of the arms I03 and I04, and in either direction of their movement,-the units A will be positioned into the path of one or the other of the engaging members carried on the shafts I01 and I08, respectively.

The totalizer'or accumulator units A are rotatably mounted on a shaft IIO carried on the arms I03 and I04, and these units are each provided with a square bushing III which has a bore IIIa through which the shaft extends. The square portion of the bushing serves as a key on which a gear I I2, a total stop disc I I 3, a. detent wheel I I4, and a type bar release disc I I5 which is provided with a notch I I8 on its periphery are secured in spaced relation with each other on. this bushing I II by means of spacing washers I I1 and are securely retained as 'a unit thereon by means of the flanges I I8. The units are mounted in spaced relation on the shaft IIO bymeans of spacing collars ,I I9 and the gear II2 of each unit is aligned for meshing engagement with the rack teeth I02 of each of the type bars 15.

When the machine is conditioned for adding operations, and the actuator shaft 34 is rocked forwardly, it will carry an ear 3 of a sector 3 therewith, (Fig. 4), and at near the limit movement of the actuator shaft, the ear 3| 4 will engage a shoulder 3I3 of a control arm 308 carried on a control member 30I and force the control arm and control member forwardly. The control member 30I being attached to the regulating device at 302,- will carry the same forwardly therewith and effect engagement of the totalizer units with the type bars. Upon the restoring movement of the actuator shaft 94", the totalizer units will remain in engagement with the type bars and the restoring movement of the type bars will-run into the totalizer, the amount set up in the keyboardi As the actuator shaft 94 nears the end of itsrestoringmovement, a pin 3I0 on the sector 3I I will engage a bifurcated portion 3I2 of the control arm 308 and restore the same and control member130l, and eil'ect'the disengage-- ment of the'totalizer from the type bars,

The total'stop disc I I3 of each of the totalizer units is provided with a peripheral lug I and is also provided with substantially diametrically opposed studs orpins I2I and I22Qrespectively,

which are secured on opposite faces of the disc.

The pins" I2I and I22 are for the purpose of tripping mechanism which coacts with. the totalizer or accumulator units for effecting a release of the actuating mechanism that controls the adjacent totalizer orac'cumulator unit of higher order. The pin I22 is adapted toengage a slide release cm I 23 (Figs? and 8) on an over-han aa meaa The type bars 15 are each provided with rack" ins arcuate arm I24 of a rockable member Ill pivotallysupported on the shaft I01 and the pin I2I is adapted to engage a cam surface I28 of an arm I21 which is pivotally supported on the transversely extending shaft I08. This arm I21 is in the form-of a bell-crank with its other leg portion I28 connected to the rockable member I by a, pin I29 fixed thereto which extends through an elongated slot opening I30 in the rockable member I25 and forms a toggle action as one or the other of the arms I24 or I21 are caused to be rocked.

The rockable member I25 is provided with an extending bent-over portion I3I which is adapted to be engaged by the extending end I32 of a slide member I33 which is carried on an adjacent driving rack 85 of higher denominational order. The slide I33 is arranged for independent sliding movement on the studs 86 and 81 by means of relatively short slot openings I34 and I35 near each end thereof (Figs. 2, 3 and 6), through which the studs extend to support and guide the same in its sliding movements on the type bars. The slide I33 is normally urged toward the front of the machine by means of a tension spring I35 which has one end fixed thereto and with its other end fixed to a link I31 which is also mounted for sliding movement on the stud 88. The stud 86 extends through a relatively short slot opening I38 in the link and is normally aligned with the slot I34 of the slide. The forward end of the link I31 is supported and guided locked position which in turn retain the driving racks 85 in their normal at-rest positions and the slide members I33 are yieldingly retained by the tension of their springs I36 against the extensions I3I of the rockable members I25. The operating movement of the actuator shaft 94 will carry the, shaft I50 therewith to engage and rock the arms I54I60 to release them from the type bars and will cause the driving racks 85 to be freely moved until the studs 88 and 81 have reached the ends 'of the slot openings I34 and I35 in the slide members I33 at which time these slide members I33 will be carried with the driving racks 85. The links I31 will also be carried with the driving racks 85 and the extensions I of the links will engage the ends I24a of the arcuate arms I24 on the rockable member, preventing a further movement of the links I31,

and'at this time the driving racks 85 will be permitted to move in advance thereof by means of the-yielding tension of the springs I36 attached to the links I31 and to the slide members I33.

During this movement of the actuator shaft 94, all of the type barsin the banks in which a key has been depressed will be released and permitted to move with the driving racks 85 until one of the steps 11 of each of the released type bars engages the lower end 330 of a coacting depressed key, which will withhold the racks from further movement. Allof the remaining type bars in the banks of higher order in which a key has not been depressed will be retained in locked position by means of the type bar stops 65, butthe driving racks 66 thereof will be moved in ad vance thereof against the tension of their springs 68. The type bars in the banks of lower order of those in which a key has been depressed will be released from their type bar stops 65 by means of the type bar stops of higher order controlling the positioning of the type bar stops of lower order upon their movement while permitting the zero stops in the banks of lower order of the ukeys depressed to remain in the path of the type bars, so that as. the machine is operated, these type bars will be permitted to move until arrested by the zero stops and position the zeros thereof in the printing line. r

The movement of the actuator shaft 94 will effect the positioning of the units of the totalizer 'A Into meshing engagement with the rack teeth I02 of the type bars15 prior to their reverse movements to run into these totalizers the amounts set up on the keyboard when adding. During total and subtotal operations, the totalizer units are brought in mesh with the type bars prior to their forward movement. The depression of the, total key 2I I or the depression of the subtotal key 2I2 effects a turning movement of the shaft I50 to present a flattened portion thereof aligned with arms. I54 sothat the rocking movements of the actuator shaft 94 will carry shaft I50 therewith and free of the arms I54. At this time, should some of the units of the totalizer be in zero position while carried into engagement with the type bars, the notches IIB of the type bar release discs I I will each receive a stud I62 fixed to the type bar lock arms I60,

and those totalizer units that are rotated upon the restoring movement of the type bars, will cause the studs I62 to ride out of the notches II6, to release the coacting type bar lock arms I60 from the type bars. If the totalizer units have been rotated during a previous operation, the peripheries of the discs II5 will then engage the studs I62 and release the arms I60 prior to the movements of the type bars. The rocking movement of'the arms I60 will carry the integral depending arms I64 therewith, and as these depending arms I54 are each provided with an extension I54a that engages the adjacent arm I54 of higher order for movement therewith, the movement ofv one of the arms I54I60 will effect movement of all of them of lower order thereof. All the arms I54 of higher order of those moved, will remain in their normal positions to retain the type bars of higher order locked against movement.

The arms I03 and I04 supporting the totalizer units, also carry a shaft I12 that has a plurality of detent pawls I thereon, which each have a relatively wide V-shaped portion '-I1I that engages a detent wheel II4 of each of the totalizer units, and these pawls are each urged into engagement with its detent wheel by a, tension spring I13 secured thereto and to a tie member 95 secured to the arms I03 and I04. These springs I13 yieldingly retain the detent wheels I I4 to retain the units of the totalizer from turning movements while permitting them to be rotated by the type bars while in engagement therewith, and the detent pawls I10 also permit the totalizer units to be rotated by a carry over mechanism which will be later described.

During adding operations, the type bars that have been released, as above described, will be carried rearwardly by means of the driving mechanism which carries the driving racks 65 rearwardly, and by means of the springs 88 the type bars are carried therewith until arrested by the depressedkeys. The rearward movement of the driving racks 65 will carry the links I31 therewith by their springs I36. When the type bars are at their limit rearward movement, the totalizer units are carried into engagement with the rack teeth I02 thereof, and prior to the re-' storing movement of the type bars, the driving racks 65 will be carried in the slots 64 of the type bars until the studs 66 of the driving racks engage the ends 64a. of the slots and positively'restore the type bars therewith. During the restoring movements of the type bars, the totalizer units will be rotated in a counter-clockwise di-' rection until the ends I02a of the rack teeth I02 have passed the gears II2 of the totalizer units, (Fig. 6), and at which time the totalizer units will be retained in the position to which they have been rotated by the detent pawls I10. Just as the ends I02m of the rack teeth I02 on the type bars are leaving the totalizer units, the extending ends I32 of the slides I33 will engage the bent-over portions I3I of the rockable members I25 and prevent further movement of the slides, while permitting the type bars to be driven by the racks 85 to their at-rest positions. During the movement of the driving racks 65 in advance of the slides I33, the studs 66 of the driving racks will engage the ends of the slot openings I36 in the links I31 and carry them therewith against the tension of their springs I36 and urge the extending ends I32 of the slides I33 against the bent-over portions I3I of the rockable members I25. Each of the slides I33 carries a pin I14a on. which a pawl or carrying member I14 is mounted and which pawl or carrying member has a toothengaging end I15, and is limited in its movements on the slide I33 by means of a pin I11 extending through a slot I16 in the pawl or carrying member, which is normally urged by means of a spring I16 with the tooth-engaging end I15 readily engageable with the gear N2 of the coacting totalizer unit.

Carry over mechanism It will be noted that during adding operations, the type bars are moved rearwardly until arrested by the ends 330. of the keys 3| engaging the steps 11 thereof, and at this time, the totalizer units are brought into engagement with the teeth I02 of the type bars, and, during the restoring movements of the type bars, the totalizer units will be rotated to extents equal to the distances of movement of the type bars. The totalizer units are rotated from their point of engagement with the rack teeth I02 to the end I02a of the teeth and should a pin I22 of the total stop disc II3 of one of the rotated totalizer units en- 'gage the cam I23 on the arm I24 of the rockable member I 25, it will rock this member I25 clockwise with the bent-over portion I3I thereof outof the path of the extending end I32 of the slide I33, and permit this slide to be instantly urged forwardly by its spring I36 with the tooth-engaging end I15 of the pawl or carryingmember I14 on the slide, into engagement with the gear II2 of the coacting totalizer unit in the adjacent bank of higher order, and rotate the same of a turn. 4

If an amount has been previously stored up in the totalizer units, and an amount is added thereto and should a pin I22 of one of the totalizer units engage the cam I23 of the rockable member I25, it will rock this member I25 in a clockwise direction prior to the time that the slide has reached it, and the slide will then pass over the bent-over portion I3I of the rockable member I25 and carry the pawl or carrying 7 member I14 therewith to engage and rotate the totalizer unit of a turn after the ends I020 of the rack teeth I02 have passed the totalizer units. It will be noted that when the bent-over portion I3I of the rockable member is in the path of movement of the slide I33, the driving rack 85 and link I31 are moved in advance thereof, and the link I31 will tension the spring I35 to urge the slide I33 against the rockable member I25 prior to the tripping thereof. When the rockable member I25 has been tripped prior to 5 the time that the slide I33 has reached it, this slide I33 will then pass over the rockable member. Whether the rockable member I25 is tripped while the slide I33 is urged thereagainst or prior to the time that the slide I33 reaches it, the pawl or carrying member I14 on the slide will eflect a rotation of the coacting totalizer unit of s of a turn.

While the totalizer units are in engagement with the type bars, (Figs. 3 and 7), the rotating movement of the totalizer unit will cause the pin I22 to engage the cam I23 and rock the member I24 in the manner as above described, or the pin I2I will engage the cam I25 of the arm I21 to rock the member I25 as the totalizer units are being restored out of mesh with the type bars.

To retain the rockable members in their normal and tripped positions, (Figs. 6 and '1), they are each provided with a bifurcated portion forming legs I42 and I48, that straddle the shaft I08 with the leg I42 provided with a notched-out portion I43 that is adapted to be engaged by a notched-out portion I45 on the free end of an arm I44 pivotally supported on a shaft I45. The arm I44 is normally urged upwardly by means of a tension spring I41 connected thereto and to the leg I48 of the rockable member I25 and retains the leg I42 and the arm I44 readily disengageable with each other and forms a locking device to retain the bent-over portion I3I of the rockable member I25 into or out of the path of the extending end I32 of the slide member I33. The arm I44 is provided with a downwardly directed extension I43 which is adapted to be engaged by the shaft I50 that is bodily carried for 0 rocking movement with the actuator shaft 34,

and when engaged, the arm I44 is rocked downwardly with the notched-out portion I45 thereof in engagement with the lower extremity 'I42aof the leg I42 to retain the rockable member I25 5 in locked position with the bent-over portion I3I higher order.

During subtraction operations, (Figs. 3 and '1), the totalizer units are brought into engage- 0 ment with the type bars prior to their rearward movement and as the type bars are moved, the totalizer units will be rotated in a clockwise direction. The type bars are moved until arrested by the depressed keys in the same manner as when adding, but the totalizer units remain in engagement therewith until the type bars are arrested, and at which time, they are carried out of engagement therewith. As the actuator shaft 34 is rocked to effect the rearward movement of the type bars, the driving racks 85, slides I33 and links I31 are carried rearwardly, and the extensions I of the links I31 engage the ends I24a of the arms I24 of the rockable members I25 and limit the rearward movements of the links I31. As the drivin racks are carthereof in the path of the adjacent slide I33 of ried their entire distances rearwardly upon each operation of the actuator shaft 34, it will be seen that when the extensions I of the links I31 engage the ends I24a of the arms I24, the springs I38 will permit of a further movement of the drivingracks 35 with the studs 35 and 81 thereof riding in the slots I34 and I35 of the slides, and exert a tension on the links I31. Should a carry over occur during these subtraction operations, the pin I22 will engage the cam I23 on the arm I24 of the rockable member I25, and rock this member in the same manner as when adding, but in this instance, the movement of the rockable member will carry the end I24a of the arm I24 thereof out of engagement with the extension I of the coacting link I31 and permit this link to be urged rearwardly by its spring I35 the distance of the length of its slot I33. This movement of the link I31 will cause the stud I43 thereon to engage an arm I13 pivoted on the shaft I12. This arm I13 of which there is one for each totalizer unit, has a spring I13 fixed thereto at its lower end and to the cross member 35, and carries a pin I13a at its upper end on which a pawl or carrying member I80 is pivotally mounted, and which is provided with a stop I8I that is urged against the arm I13 by means of a spring I82. The pawl or carrying member I80 is normally retained out of engagement with the gear II2 of the totalizer unit by means of the spring I13 on the arm I13, and as the links I31 are carried rearwardly, as above described, the studs I thereon will be brought into engagement with these arms I13, but will not effect movement thereof by reason of the extensions I31 of these links engaging the ends I24a of the rockable members. As a pin I22 of a totalizer unit engages the cam I23 to rock the rockable member I25, the end I24a of the arm I24 thereof will be moved out of the path of the extension I4I of the coacting link and permit this link to be instantly urged rearwardly by its spring I35, and the stud I40 of the link will effect a clockwise rocking movement of the arm I13 to engage the pawl or carrying member I80 with the gear I I2 of the totalizer unit. This engagement of the pawl or carrying member I80 with the gear 2- of the totalizer unit takes place at near the limit rearwardmovement of the driving racks 85, which permits of the complete settingup of the type bars and rotation of the totalizer units prior to the time that the link I31 is released from the rockable member I25, so that the carry over movement of the totalizer unit will occur and.

rotate the adjacent unit of lower order of a turn. The rockable member I25 is retained in the position to which it has been rocked by means of the arm I44 engaging the leg I42 thereof and as the actuator shaft is restored to its normal position, the shaft I carried therewith will engage and rock the arm I44 and permit the rockable member I25 to be spring-urged by the spring I41 to normal position. The total stop disc I13 of each of the totalizer units is provided with a peripheral lug I20 which is adapted to be engaged by a hook-like portion I54 of a total stop arm I53 that is mounted for rocking movement on the shaft I05 and aligned with a totalizer unit, and which arms are normally retained out of the path of the lugs I20. The lower portions of the total stop arms I53 are each provided with an extension I55 which rests on a floating transversely extending shaft I55 carried for bodily movement on the shaft I05 by means of links I51. Each total stop arm I53 is yieldingly retained with its extension I65 in contact with the shaft I66 by means of a torsion spring I68 which has its body portion encircling the shaft I06 and with its free ends engaging the shaft I66 and the extension IGIa of the arm I63 to permit oi an independent yieldable rocking action of each of the arms I63.

It will be noted that a total stop arm I63 coacts with the lug I20 of a total stop disc H3 01 each totalizer unit, but these not move therewith as the totalizer units are moved into and out of meshing engagement with the rack teeth I02 of the type bars I5, but are arranged to coact with the totalizer in either their normal or raised positions.
